I use dd-wrt as my home router setup and that's been working fine. Now I wanted to figure out a way to be able to use my iPad to set up a IPSec tunnel to my home network while I'm on the road.

PPTP is pretty much insecure at this point so I want to use something IPSec based. Based on what I can find, dd-wrt does not support IPSec. So I thought it might be possible to set up a linux box with racoon in my home network as the VPN terminator.
